Detailed Description

An observable class for the requirement of tree level perturbative unitarity.

This class is used to require the unitarity for all the tree level scalar-scalar scattering amplitudes. The 12 eigenvalues of the S-matrix can be found in [7],Ginzburg:2005dt. They should be smaller than \(8\pi\) in magnitude to preserve unitarity of the S-matrix, however corresponding two-loop calculations in the SM show that a more reasonable upper bound on their absolute values would be \(2\pi\) (see discussion in [22]).
